The University of California, Riverside (UCR) and the University of Michigan, in collaboration with industry partners, have initiated the Hydrogen Engine Alliance of North America (H2EA-NA) to advocate for hydrogen as a viable alternative fuel for internal combustion engines (ICEs). This alliance aims to leverage hydrogen's potential to power various vehicles and equipment, including large marine engines, and contribute to reducing climate change emissions like carbon dioxide and pollutants. The co-directors of H2EA-NA, Georgios Karavalakis and Wayne Miller from UCR, along with André Boehman from the University of Michigan, are leading efforts to promote hydrogen-powered ICEs as a long-term, reliable solution complementing electric and zero-emission technologies. The recent demonstration by Southwest Research Institute showcased the ultra-low emissions of nitrogen oxides from a heavy-duty truck utilizing hydrogen ICE technology, indicating a significant reduction in emissions compared to traditional diesel-powered vehicles. By emphasizing hydrogen as a low-carbon solution for sectors where electrification is not currently viable, the alliance aims to foster innovation and collaboration to advance the hydrogen ecosystem and transportation goals in North America. While countries like China, Germany, and Japan have led in hydrogen fuel development, the U.S. faces challenges in infrastructure, policy, and public awareness, hindering progress in hydrogen innovation. H2EA-NA plans to address these barriers through educational initiatives, industry partnerships, and financial support generated from membership fees. By creating a platform for knowledge sharing, technology advancement, and market trend awareness, the alliance aims to propel the adoption of hydrogen-powered ICEs in the U.S. and enhance the country's position in hydrogen fuel innovation. The establishment of H2EA-NA signifies a collaborative effort to drive sustainable solutions, reduce emissions, and promote the benefits of hydrogen as a clean energy alternative within the transportation sector.
